You can avoid the 'how large will it end up' problem (which I readily
recognise) by making a row robin and stipulating the width of the rows
and the sashings. Bit more regulatory, but no hard feelings afterwards!

I'm taking part in a row robin at the moment, it's been determined that
the width of each row must be 48inches and that the height must be
between 6 and 8 inches, the rows are kept separate until the end and
then it's the owners choice whether or not to add sashing. We were
supposed to include a background fabric and any others we want used, so
I included 2 yards of my chosen background and kept a yard back for
sashing and/or inner borders. I also included a tricky colour match from
border fabric I'd already chosen, a piece of the border fabric so people
could see it and the remains of a FQ I'd used. The only box I've
received so far didn't really have a specific background, but was
gorgeous green and cranberry batiks.

It really is going to be a challenge, deciding on my own was tricky, I
ended up doing 2 each of 3 basket blocks and diagonally setting them,
and setting the theme for the quilt to be flowers. The first I received
was easy as the only theme was batiks and there was plenty in the box,
but I know coming up I've got transport (the first row was a foundation
pieced train), 19th century fabrics and blocks, and I can't remember
what else, we have two groups in parallel, so I'm not entirely sure
which ones are in my group.
